Spectrum requires that I use their newest modem. It only has one ethernet port which plugs into a separate Spectrum router. That router has four additional ethernet ports, one of which connects to my Deco M4 and I use the other ports for various other wired connections. I obviously do not need their router for wifi, but I do need the additional ethernet ports as both of my Deco ethernet ports are currently in use (one to connect to the Spectrum router, one to connect a second Deco with a wired connection). Spectrum modem>Spectrum router>Deco M4
I tried replacing the Spectrum router with a TP-Link ethernet switch. The port lights on the switch indicate that there is throughout, but there in no internet connectivity on my Deco (solid red light). Spectrum modem>TP-Link switch>Deco M4
I would like to remove the Spectrum router if possible. I don't need it for wifi and also Spectrum said I could send it back and knock some $ off my monthly bill. All it really is at this point is a pass through. But I do need the additional ethernet ports.
